Cleaning mechanism of belt conveyor

Abstract

The invention relates to a lubricating, cleaning or clearing device, in particular to a cleaning mechanism of a belt conveyor. The cleaning mechanism comprises a scraping plate, a scraping piece mounted on the scraping plate, and an automatic compensation structure, the automatic compensation structure comprises a sleeve, glands, a screw rod, a compression spring, a supporting spring and a connecting rod, elastic coefficient of the compression spring is larger than that of the supporting spring, the sleeve is fixed on a rack, the screw rod and the connecting rod extends into the sleeve from two ends of the sleeve respectively, the glands are arranged at the extending-in ends of the screw rod and the connecting rod respectively, the compression spring is positioned between the glands, the supporting spring externally sleeves the connecting rod, one end of the supporting spring is supported on the glands while the other end is arranged on the inner wall of the sleeve, and one end, away from the glands, of the connecting rod is connected with the scraping plate. When the cleaning mechanism is in use, the scraping piece can constantly contact with the surface of a belt, so that good cleaning effect is guaranteed.

Description

technical field [0001] The invention relates to a lubricating, cleaning or cleaning device, in particular to a cleaning mechanism of a belt conveyor. Background technique [0002] The production of low-iron soda sulfide mainly uses coke powder as the reducing agent, and uses chromium-containing Glauber's salt and dehydrated Glauber's salt as raw materials for industrial production. The production process mainly includes material preparation and loading process, calcination process, billet slag washing process, sedimentation and mud washing process, low iron sulfide alkali liquid preparation process, evaporation process, tablet production and packaging process. [0003] In the material preparation and loading process, the thenardite needs to be fed by a belt conveyor. During the feeding process, the thenardite will stick to the feeding side of the belt. When the feeding side faces downward, the thenardite will fall off for a while. Therefore, there are scrapers. The existing...

Problems solved by technology

[0003] In the material preparation and loading process, the thenardite needs to be fed by a belt conveyor. During the feeding process, the thenardite will stick to the feeding side of the belt. When the feeding side faces downward, the thenardite will fall off for a while. Therefore, there is a scraper. The existing scraper is usually fixed on the frame, and the cleaning scraper on it is in contact with the belt by its own weight or counterweight. It is divided into two types: H type and V type. When the belt runs, the coal stuck on the belt is scraped off and discharged to the outside of the belt. Since the belt scraper is fixed on the frame, the distance from the belt has been fixed. After a period of use, the scraper on the scraper will The scraper will wear out and cannot touch the surface of the belt, so the scraper will lose its effect, and the purpose of cleaning the surface of the belt will not be achieved
